Abstract

Purpose: The authors reviewed their experience using the transanal Soave technique, to determine (1) if it offers any advantages over the standard open approach and (2) whether routine laparoscopic visualization is necessary. Methods: The case reports of 37 consecutive children less than 3 years old undergoing Soave pull-through were reviewed. Patients were excluded from analysis if they had total colon disease or had a previous colostomy. The patients were divided into 3 groups: open Soave (OS, n = 13), transanal Soave with routine laparoscopic visualization (LVS, n = 9), and transanal Soave with selective laparoscopy or minilaparotomy (TAS, n = 15). Cost was calculated based on hospital stay, operating room time, and use of laparoscopic equipment. Results: In the TAS group, suspicion of a longer segment led to the selective use of laparoscopy with or without biopsy in 2 children, and the use of a small umbilical incision for mobilization of the splenic flexure in 2. There were no differences among groups with respect to age, weight, gender, transition zone, operating time, blood loss, intraoperative complications, enterocolitis, or stricture or cuff narrowing. Hospital stay was significantly longer in the OS group (median, 7 days; range, 3 to 47) than the LVS (median, 1; range 1 to 6) or TAS (median, 1, range, 1 to 3) groups. Cost (in thousands of dollars) was also higher in the OS group (median, 6.9; range, 3.9-25.7) than the LVS (median, 3.9; range, 3.6 to 6.4) or TAS (median, 3.4; range, 2.2 to 9.4) groups. Repeat surgery was necessary for 4 OS patients: 2 adhesive small bowel obstructions (1 of whom died), 1 twisted pull-through, and 1 recurrent aganglionosis. Three TAS patients required repeat surgery: 1 twisted pull-through, 1 anastomotic leak, and 1 cuff narrowing. Conclusions: These data suggest that the transanal pull-through is associated with a significantly shorter hospital stay and lower cost than the open approach, without an increased risk of complications. Because there is no intraabdominal dissection, there probably is a lower incidence of adhesive bowel obstruction. Routine laparoscopic visualization or minilaparotomy is not necessary but should be used in children who are at higher risk for long segment disease. J Pediatr Surg 35:820-822.

Materials and methods

The patient population consisted of all children less than 3 years of age who underwent a Soave pull-through over a 7-year period. Surgical approach was determined by surgeon preference. Patients were excluded from the study if they had total colon disease or had a previous colostomy, leaving 37 children for analysis. The patients were divided retrospectively into 3 groups: open Soave (OS), transanal Soave with routine laparoscopic visualization (LVS), and transanal Soave with selective

Results

There were 13 patients in the open Soave (OS) group, 9 in the group undergoing a transanal Soave with routine laparoscopic visualization (LVS), and 15 in the transanal Soave with selective laparoscopy or minilaparotomy (TAS) group. Of the 15 children in the latter group, 11 underwent a transanal pull-through alone. Two underwent laparoscopy with biopsy before beginning the perineal dissection, because female gender and a strong family history raised suspicion of long segment disease

Discussion

These data suggest that the 1-stage Soave procedure using a transanal technique is associated with a similar rate of postoperative complications as the same procedure done using an open approach. However, the transanal approach has the advantages of a significantly shorter hospital stay, less need for narcotic analgesics, and lower cost when compared with the open approach.

We have not compared the transanal approach to the various laparoscopic procedures that are becoming increasingly popular.

    However, there are concerns that TERPT causes more anal sphincter damage because the exposure of the anal canal is longer and more forceful when the whole operation is performed through the anus [5–7]. The literature comparing bowel function after total transanal and transabdominal ERPT procedures is inconclusive [4,8-11]. Transabdominal ERPT includes operations assisted with both laparoscopy and laparotomy, but these entities are not necessarily identical with respect to preservation of the anal sphincters.

    This increased risk after laparotomy-assisted TERPT can be explained by a few factors: first, a selection bias, introduced by the fact that surgeons will more likely opt for laparotomic-assistance in complex patients. Secondly, some surgeons find the mobilization of the splenic flexure more challenging during laparotomic-assistance, potentially resulting in more traction on the anastomosis, compared to colonic mobilization of the splenic flexure via laparoscopy [29,30]. Thirdly, laparotomic-assistance was used more frequently during implementation of the TERPT, when the surgeons were less familiar with the technique, which could have introduced a bias caused by the learning curve of the technique rather than the laparotomic approach that may have led to a higher complication rate [27].

    There was a significant difference in surgery duration between groups, with CTP being completed in less time than LATP (2.6 ± 0.6 h vs. 3.9 ± 1.1 h, p = 0.001). The literature search yielded 423 abstracts, from which 17 articles (12 LATP [12–23], 3 CTP [24–26], and 2 comparative [27,28]) were included (Fig. 1). The main reasons for study exclusion were surgical procedures and outcomes that were not of relevance for this review.
